Homework Help: Angluar motion

  1. Apr 13, 2008 #1
    1. A wheel 2.00m in diameter lies in a vertical plane and rotates with a constant angular acceleration of 4.00 rad/s^2. The wheel starts at rest at t=0, and the radius vector of a certain point P on the rim makes an angle of 57.3 with the horizontal at this time. At t=2, find the angular speed of the wheel, the tangential speed and the total acceleration of the point P, and the angular position of the point P.

    3. for the speed I times the acceleration with the time to get 8 rad/s. The rest i don't understand so whatever help you could give will be grateful. Thanks.
